A CGRPORATION OF PRESS.

Application filed February 18, 1918. Serial No. 217,858.

To aZZwhom it may concern:

Be it known that I, BURTON N. CLARY, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Presses, of which the following description, in connection with the accompanying drawings, is a specification llke reference characters on the drawings indica ting like parts in the several figures.

This invention relates to presses and 1s herein illustrated as embodied in a deviceespecially designed for applylng pressure to a pile of veneered soles.

It is customary in the manufacture of certain kinds of shoes to cement a tap to the sole thereby producing a so-called veneered sole. Commonly the taps are coated with cement and laid on the soles. The composite blanks thus formed are then stacked and the pile subjected to pressure for a sufficient interval to permit the cement toset.

The general object of the present 1nvention is to provide a simple and inexpensive device by the use of which pressure may be applied to a pile of blanks and the pressure maintained for a desired. interval.

According to one feature of the invention, the supports which engage the ends of the pile are connected by a flexible member in such manner that pulling upon one end of the flexible member draws the supports toward each other so as to apply pressureto the pile, means being prov1ded for maintaining the pressure thus applied. Conveniently the supports may be short boards or blocks and the flexible member a thin iron band which passes through a one-way catch, force being applied to the band to draw it to the desired extent through the catch by means of a lever fulcrumed on one of the blocks and provided with means for gripping the band.

This and other features of the invention, including certain details of construction and combinations of parts, will be described as embodied in an illustrative machine and pointed out in the appended claims.

Referring now to the accompanymg draw hig. 1 is an elevation of a device in which the present invention is embodied, and

Fig. 2 is a perspective of a portlon of the upper part of the device.

The pile of soles or other blanks 3 is ens iii block 5, as best shown in Fig. l.

gaged at its ends by supports in the form of wooden blocks 5, 7. Fast to the upper block 5 is a member 9 having at one end ears 11 which support the pivot 13 of a dog 15 which is urged at all times by a coiled spring 17 to turn in a counter-clockwise direction about the axis of the pivot 18. Beneath the dog and fast to or integral with the member 9 is a member 19 having an inclined upper face toward which the lower end of the dog 15 is urged by the spring 17. The construction just described forms a one-way catch through which passes a flexible, preferably selfsustaining member in the form of a thin, narrow iron band 21 one end of which is fastened to the casting 9, and hence to the This flexible band runs down around the lower block 7 and then up through the one-waycatch. If, therefore, force is applied to the free end of the flexible band to pull or draw it through the catch, the blocks will be caused to approach and pressure thus applied to the pile of blanks. At the same time whatever pressure is applied will be maintained by the action of the catch which will permit free movement of the band in a direction to increase the pressure upon the blanks but will prevent movement in the opposite direction. in order to provide means for releasing the catch when desired, a tail 23 is formed on the dog 15 depression of which will raise the dog and permit the flexible hand to become slack.

Formed on that end of the member 9 re mote from the oneway catch is a seat 25 which serves as a fulcrum for a pulling member in the form of a'bent lever 27, the seat 25 being formed to receive the suitably shaped end of the lever. The illustrative lever is made in two parts, a lower U-shaped part having a cylindrical base 29, adapted to fit in the seat 25, and a handle bent at approximately right angles to the U-shaped member and pivoted to said member at 31. The pivoted end of the handle is rounded off as indicated at 33 and is adapted to co-operate with a bar 85 fast to the arms of the U- shaped member and having a rounded-off upper face. The free end of the flexible band passes between the rounded end 33 of the handle and the bar 35 and when the pulling member 27 is swung to the left the band is gripped and drawn through the one-way catch. When the pulling member is swung to the right the flexible band is released. As the pulling member is oscillated it thus acts as an intermittent grip device to tighten the band by intermittent pulls and apply pressure to the pile oi blanks. It should be noted that the pulling member may be detached at any time by tilting the handle upwardly about the pivot 31 and sliding the member off the end of the flexible band. This is a desirable feature in a sole press, since the soles must stand under pressure for several hours to permit the cement to set; and with the pulling member made detachable the compressed soles occupy less space than they would otherwise, and only one pulling member is necessary for a plurality of otherwise complete presses.

In the operation of the device the cement-- ed soles are placed in the press while the flexible band is slack. The pulling member is then manipulated to tighten the band. the one-way catch maintaining the band taut and preserving the pressure which is applied to the soles. After the desired pressure has been secured, the pulling member may be removed or not as may be desired after which the compressedsoles are set aside for an interval. hen a proper interval has elapsed to ensure the setting of the cement, the catch is released by pressure or a light blow upon the tail 23. It should be noted that the fulcrum or seat for the bent pulling lever is located near one end of the block or support as embodied in a particular device it should be understood that the invention is not limited in the scope of its application to the particular device which has been shown and de scribed and that certain parts, for example the lower block, might be dispensed with under some circumstances.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

l. A device for applying pressure to a pile of i'iat blanks, having, in combination, a flat block adapted to rest upon one end of the pile, an upstanding abutment thereon to furnish a seat for a separate pulling member and a one-way catch mounted on the block, and a flexible member attached at one end to the bloclrconstructed and arranged to pass around a second fiat block at the other end of the pile and have its free end extending through the catch into proximity to the seat to be engaged by the pulling member.

2. A press for applying pressure to a flat pile of blanks having, in combination, flat supper for engaging the ends of the pile, a self-sustaining flexible member connected to one support and passed about the other support and then back to the first, a lever arranged to be fulcrumed on said first sup?
